Replacing the battery, to be recycled or disposed of in a proper manner.

Replacing the battery Your computer has a special type of memory that maintains the date, time, and settings for built-in features, such as serial- and parallel-port assignments (configuration). A battery keeps this information active when you turn off the computer. The battery requires no charging or maintenance throughout its life; however, no battery lasts forever. If the battery fails, the date, time, and configuration information are lost, and an error message is displayed when you turn on the computer. Refer to "Lithium battery notice" on page xii for information about replacing the battery. Note: If Enhanced Security is enabled, the administrator password is not lost when the battery fails. If you replace the original lithium battery with a heavy-metal battery or a battery with heavy-metal components, be aware of the following environmental consideration. Batteries and accumulators that contain heavy metals must not be disposed of with normal domestic waste. They will be taken back free of charge by the manufacturer, distributor, or representative, to be recycled or disposed of in a proper manner. For further information on battery disposal, call IBM at 1-800-IBM-4333 (1-800-426-4333) in the U.S. For information outside of the U.S., contact your IBM reseller or marketing representative. To change the battery: 1. Turn off the computer and all attached devices. 2. Unplug the power cord. 3. Remove the cover. See "Removing the cover and front bezel" on page 59. Chapter 6.
